	public boolean onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ) {
		...
		IBlockState var9 = worldIn.getBlockState(pos);
		...
		// It's supposed to check if the block it was placed one is a fence. How ever it's checking the BlockState, not the block.
		// What was meant to be done is var9.getBlock() instead of just var9.
		if(side == EnumFacing.UP && var9 instanceof BlockFence) {
			// Offset for the spawn
